One of the greatest tragedies of the gutting of the federal government is the loss of dedicated scientists who chose to work in public service for the benefit of the American people.
This letter is both incredibly brave and a testament to their integrity.

Stopping #PEPFAR is anything but America 1st and here’s why (from a US perspective). Over the last 20 years working in Africa, I’ve watched China make massive gains here while PEPFAR has saved millions of lives and kept America influential. Cutting it now is a grave mistake.

Acute HIV infection (AHI) detection is challenging in most populations due to low prevalence. However, we show in our new paper in JAIDS that using risk score algorithms in STI clinics in Malawi can greatly improve the efficiency of AHI detection.
